7. History of Intel x86 processors • 4004: 4-bit processor; 8-bit processors 8080, 8085. • 8086: 16-bit processors, introduced in 1979: 20-bit address bus (AB), 16-bit data bus (DB), 5/8/10 MHz. • 80186: a faster version of the 8086. Also 20-bit AB and 16-bit DB. Never widely used in computer systems. • 80286: introduced in 1982, It has a 24-bit AB, which implies 16MB of memory address space. • 80386: Intel introduced its first 32-bit processor in the 1985. It has 32-bit AB and 32-bit DB. It follows their 32-bit architecture known as IA-32. • Pentium: was introduced in 1993 (20th anniversary). it uses a 64-bit wide DB, 60/66 MHz. • Itanium: 64-bit processor, released in 2001; formerly called IA-64, the Itanium uses a 64-bit AB to provide substantially larger address space. Its DB is 128 bits wide.
